I have the sleep problem too, but assumed it was in my head. but after making my own subject about this in a different dialog, I found out I am not the only one.
I remember my doctor who diagnosed me with Lupus in 1996, gave me elavil. I assumed it was for a psychotic break, and I knew I was not crazy, just unable to sleep. My father was paranoid schizophrenic, and he was on Elavil at different times. I was assuming that the doctor was thinking I was schizoid, a mental thing, instead of it being Lupus.
I know your feeling however of sleepless nights, and exhausted and irritable the next day. Luckily for me a young woman on another list was able to identify a cycle for me. Said that about the fourth of the month, I went into these good mental states, and around the 14, or 15, I no longer had them, for another period during the month.
The times that I can't sleep, my brain fog leaves me and I can think well, and remember things better. i assumed it was mental. so glad to know that it isn't. It is easier to accept knowing that it isn't in my head.
Thank you all for being just as you are.
